Abstract

Life-cycle, delimitation and redescription ofCatatropis verrucosa (Friilich, 1789) Odhner, 1905 (Trematoda: Notocotylidae) I. Kanev, I. Vassilev, V. Dimitrov and V. Radev Abstract The life-cycle of Catatropis verrucosa (Fr6lich, 1789) Odhner, 1905 has been completed experimentally starting from infected snails collected along the River Danube in Europe. Each stage of the life-cycle is redescribed. Taxonomic problems are discussed and the main features of the species are listed. Synonyms for C. verrucosa are Fasciola verrucosa Fr61ich,

Catatropis pakistanensis n. sp. (Trematoda: Notocotylidae) from Northern shovelers, Anas clypeata (Anatidae: Aves) from Pakistan with some remarks on the history of Catatropis species

“…However, Odening's C. verrucosa possessed only 8 ventral papillae in each ventral lateral row and in terms of the high intermediate host specificy of notocotylids these findings strongly contradicted the results of Erkina. Experimental infections of 9 bird species (including ducks, geese, chicken, turkey, partridges and quails) with C. verrucosa deriving from larval stages shed by naturally infected B. tentaculata and B. leachi collected along the River Danube in Austria and Bulgaria Kanev et al (1994) supported the opinion of Russian helminthologists. The authors also successfully infected both Bithynia species but attempts to infect lymnaeid and planorbid snails failed.…”

“…C. chandarii Skrjabin, 1915 is now considered a synonym of C. verrucosa (Filimonova 1985, Kanev et al 1994 and C. filamentis Barker, 1915, C. gallinulae Johnston, 1928and C. pacifera Noble, 1933 were removed from the genus because of an unproper structure of the median ridge while C. johnstoni Martin, 1956 andC. nicolli Cribb, 1991 were withdrawn owing their lack of bilateral rows of ventral papillae (Bayssade-Dufour et al, 1996).…”

“…Soon after, Zeder (1800) assigned this worm to the genus Monostomum. The scientific history of this fluke was described in detail by Kanev et al (1994). After comparing his own trematode material collected in Sweden with monostomes of the private collection of Arthur Looss from Cairo, Egypt, and flukes from the museal collection in Greifswald, Germany, Odner (1905) established the genus Catatropis to delineate monostome digeneans with ventral structures of the 'verrucosa' type from those with 3 rows of evertable ventral spherical papilliform protrusions.…”

“…Los helmintos recolectados fueron preservados en etanol 70% y transparentados en Lactofenol de Amman. Los parásitos fueron identificados mediante las claves taxonómicas de Anderson et al (1989), Jones et al (2005), Cram (1927), Kanev et al (1994), Khalil et al (1994), Schell (1985), Seurat (1918), Travassos 1915y Travassos et al (1969 e incorporados a la colección de la Unidad de Parasitología Veterinaria de la Universidad Austral de Chile (992 Parasitol.

“…Catatropis verrucosa presenta un cuerpo elongado con una cresta continua central asociada a 2 hileras de 11 papilas ventrales, además de la presencia de 1 única ventosa oral. El ovario es central y los testículos se ubican laterales a éste en el tercio posterior del cuerpo (Jones et al (2005); Kanev et al, 1994;Schell, 1985;Travassos et al, 1969). Echinostoma revolutum s.l.…”
